Implications Of Rice Cultivar Selection To Optimize Returns From Crop Insurance, David Ethan Branscum
Graduate Theses and Dissertations
Rice production differs from most other field crops by distinct differences in yields across cultivars and rice producers being paid for yield after post-harvest milling. Using eleven years (2003-2013) of Arkansas harvest data from performance trials in six different locations, hybrids have 19% higher paddy yields and head rice yield rate 1.7% lower than conventional cultivars. Given the 2014 Farm Bill’s emphasis on crop insurance as a risk management tool for producers, these variations in yield among cultivars have significant implications for rice producers. Comparing national level, crop insurance data on corn, soybeans and rice indicates rice producers strongly prefer …

Food and Machinery
The physicochemical and emulsifying properties of pork myobrillar protein (MP) solution treated by ultrasound power: 0, 80, 140, 180 and 200 W were examined. Compared with MP without ultrasonic treatment, with the increase of ultrasonic power, d4, 3 of MP decreased, while solubility, absolute value of the zeta potential, emulsifying activity and emulsion stability were significantly increased. Meanwhile 180 W was the optimum ultrasound power to obtain the highest emulsifying activity index (EAI) and emulsion stability index (ESI). The increase of emulsion stability was related to increased zeta potential and reduced average particle size. Optical microscopy observation proved that …

Taking the luteolin, apigenin and carnelin in the chrysanthemum as the determination index, the high-performance thin-layer scanning method (HTLCS) and high-performance liquid chromatography (HPLC) were used to determine the linear relationship between each method. The linear relationship and range of each method were investigated. The results showed that the established HTLSC and HPLC methods met the requirements, and the linear relationship was good, RE<3%. However, there was no significant difference between the two methods (P>0.05). The method of establishing HTLCS and HPLC method was reasonable. The determination of three components of luteolin, apigenin and acacetin could be carried out by using HTLCS instead of HPLC.
